I'am working with rocks on the granulite-amphibolite interphase, closely
associated with migmatites. I am trying to calculated the P-T conditions
using multi-equilibrium analisys, using the TWQEEU. As I don't have direct
information on the H2O and CO2 activities, I have some doubts on have to
proceed, and wich criterias can be usefult to correcly select this
activities. If you can help me with references or some useful criterias, I
will be really greatful.
Thanks
Diana
